| 1 | Highly active zigzag-like Pt-Zn alloy nanowires with high-index facets for alcohol electrooxidation显示文摘The development of highly efficient Pt-based alloy nanocatalysts is important but remains challenging for fuel cells commercialization.Here,a new class of zigzag-like platinum-zinc (Pt-Zn) alloy nanowires (NWs) with rough surface and controllable composition is reported.The merits of anisotropic one-dimensional nanostructure,stable high-index facets and coordinatively unsaturated Pt sites endow the composition-optimal Pt94Zn6 NWs with a mass activity of 7.2 and 6.2 times higher than that of commercial Pt black catalysts toward methanol/ethanol oxidation,respectively.Alloying-induced d-band electron modulation and lattice strain effects weaken the adsorption strength of poisoning species,which originally enhances the catalytic activity of Pt-Zn NWs.This study provides a new perspective of Pt-Zn electrocatalysts with intrinsic mechanism for enhanced catalytic performance. | Yanchao Xu Xiaoqiang Cui Shuting Wei Qinghua Zhang Lin Gu Fanqi Meng Jinchang Fan Weitao Zheng | 2019 | Nano Research2019，12，5： | 7 |
| 2 | An epidermal sEMG tattoo-like patch as a new human–machine interface for patients with loss of voice显示文摘Throat cancer treatment involves surgical removal of the tumor,leaving patients with facial disfigurement as well as temporary or permanent loss of voice.Surface electromyography(sEMG)generated from the jaw contains lots of voice information.However,it is difficult to record because of not only the weakness of the signals but also the steep skin curvature.This paper demonstrates the design of an imperceptible,flexible epidermal sEMG tattoo-like patch with the thickness of less than 10μm and peeling strength of larger than 1N cm−1 that exhibits large adhesiveness to complex biological surfaces and is thus capable of sEMG recording for silent speech recognition.When a tester speaks silently,the patch shows excellent performance in recording the sEMG signals from three muscle channels and recognizing those frequently used instructions with high accuracy by using the wavelet decomposition and pattern recognization.The average accuracy of action instructions can reach up to 89.04%,and the average accuracy of emotion instructions is as high as 92.33%.To demonstrate the functionality of tattoo-like patches as a new human–machine interface(HMI)for patients with loss of voice,the intelligent silent speech recognition,voice synthesis,and virtual interaction have been implemented,which are of great importance in helping these patients communicate with people and make life more enjoyable. | Huicong Liu Wei Dong Yunfei Li Fanqi Li Jiangjun Geng Minglu Zhu Tao Chen Hongmiao Zhang Lining Sun Chengkuo Lee | 2020 | Microsystems & Nanoengineering2020，6，1： | 6 |
| 3 | 1000 Wh L^(-1)lithium-ion batteries enabled by crosslink-shrunk tough carbon encapsulated silicon microparticle anodes显示文摘Microparticulate silicon(Si),normally shelled with carbons,features higher tap density and less interfacial side reactions compared to its nanosized counterpart,showing great potential to be applied as high-energy lithium-ion battery anodes.However,localized high stress generated during fabrication and particularly,under operating,could induce cracking of carbon shells and release pulverized nanoparticles,significantly deteriorating its electrochemical performance.Here we design a strong yet ductile carbon cage from an easily processing capillary shrinkage of graphene hydrogel followed by precise tailoring of inner voids.Such a structure,analog to the stable structure of plant cells,presents‘imperfection-tolerance’to volume variation of irregular Si microparticles,maintaining the electrode integrity over 1000 cycles with Coulombic efficiency over 99.5%.This design enables the use of a dense and thick(3 m Ah cm^(-2))microparticulate Si anode with an ultra-high volumetric energy density of 1048 Wh L^(-1)achieved at pouch full-cell level coupled with a Li Ni_(0.8)Co_(0.1)Mn_(0.1)O_(2)cathode. | Fanqi Chen Junwei Han Debin Kong Yifei Yuan Jing Xiao Shichao Wu Dai-Ming Tang Yaqian Deng Wei Lv Jun Lu Feiyu Kang Quan-Hong Yang | 2021 | National Science Review2021，8，9： | 4 |
| 4 | Electron-Deficient Zn-N_(6) Configuration Enabling Polymeric Carbon Nitride for Visible-Light Photocatalytic Overall Water Splitting显示文摘Despite of suitable band structures for harvesting solar light and driving water redox reactions,polymeric carbon nitride(PCN)has suffered from poor charge transfer ability and sluggish surface reaction kinetics,which limit its photocatalytic activity for water splitting.Herein,atomically dispersed Zn-coordinated three-dimensional(3D)sponge-like PCN(Zn-PCN)is synthesized through a novel intermediate coordination strategy.Advanced characterizations and theoretical calculations well evidence that Zn single atoms are coordinated and stabilized on PCN in the form of Zn-N_(6) configura-tion featured with an electron-deficient state.Such an electronic configuration has been demonstrated contributive to promoted electron excitation,accelerated charge separation and transfer as well as reduced water redox barriers.Further benefited from the abundant surface active sites derived from the 3D porous structure,Zn-PCN realizes visible-light photocatalysis for overall water splitting with H_(2) and O_(2) simultaneously evolved at a stoichiometric ratio of 2:1.This work brings new insights into the design of novel single-atom photocatalysts by deepening the understanding of electronic configurations and reactive sites favorable to excellent photocatalysis for water splitting and related solar energy conversion reactions. | Daming Zhao Yiqing Wang Chung-Li Dong Fanqi Meng Yu-Cheng Huang Qinghua Zhang Lin Gu Lan Liu Shaohua Shen | 2022 | Nano-Micro Letters2022，14，12： | 2 |
| 5 | Balance control of grid currents for UPQC under unbalanced loads based on matching-ratio compensation algorithm显示文摘In three-phase four-wire systems, unbalanced loads can cause grid currents to be unbalanced, and this may cause the neutral point potential on the grid side to shift. The neutral point potential shift will worsen the control precision as well as the performance of the threephase four-wire unified power quality conditioner(UPQC),and it also leads to unbalanced three-phase output voltage,even causing damage to electric equipment. To deal with unbalanced loads, this paper proposes a matching-ratio compensation algorithm(MCA) for the fundamental active component of load currents, and by employing this MCA,balanced three-phase grid currents can be realized under 100% unbalanced loads. The steady-state fluctuation and the transient drop of the DC bus voltage can also be restrained. This paper establishes the mathematical model of the UPQC, analyzes the mechanism of the DC bus voltage fluctuations, and elaborates the interaction between unbalanced grid currents and DC bus voltage fluctuations;two control strategies of UPQC under three-phase stationary coordinate based on the MCA are given, and finally, the feasibility and effectiveness of the proposed control strategy are verified by experiment results. | Xiaojun ZHAO Chunjiang ZHANG Xiuhui CHAI Jinlong ZHANG Fanqi LIU Zhe ZHANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，6： | 2 |
| 6 | Quasi-two-dimensionalβ-Ga2O3 field effect transistors with large drain current density and low contact resistance via controlled formation of interfacial oxygen vacancies显示文摘Quasi-two-dimensi on al(2D)β-Ga2O3 is a rediscovered metal-oxide semiconductor with an ultra-wide bandgap of 4.6-4.9eV.It has been reported to be a promising material for next-generation power and radio frequency electronics.Field effect transistors(FETs)that can switch at high voltage are key compone nts in power and radio frequency devices,and reliable Ohmic con tacts are essential for high FET performance.However,obtaining low contact resistance onβ-Ga2O3 FETs is difficult since reactions betweenβ-Ga2O3 and metal contacts are not fully understood.Herein,we experimentally demonstrate the importanee of reactions at the metal/β-Ga2O3 interface and the corresponding effects of these reactions on FET performance.When Ti is employed as the metal contact,annealing ofβ-Ga2O3 FETs in argon can effectively transform Schottky contacts into Ohmic contacts and permit a large drain current density of-3.1 mA//μm.The contact resistance(Rcontact)between the Ti electrodes andβ-Ga2O3 decreased from^430 to^0.387Ω·mm after annealing.X-ray photoelectron spectroscopy(XPS)confirmed the formation of oxygen vacancies at the Ti/β-Ga2O3 interface after annealing,which is believed to cause the improved FET performance.The results of this study pave the way for greater application ofβ-Ga2O3 in electronics. | Zhen Li Yihang Liu Anyi Zhang Qingzhou Liu Chenfei Shen Fanqi Wu Chi Xu Mingrui Chen Hongyu Fu Chongwu Zhou | 2019 | Nano Research2019，12，1： | 2 |
| 7 | Frequency regulation in alternation-current transports across metal to insulator transitions of thin film correlated perovskite nickelates显示文摘Although the metal to insulator transition(MIT)observed in d-band correlated metal oxides enables promising applications(e.g.,correlated logical devices and Mottronic devices),its present recognition is mainly limited on the direct current(DC)electrical transports.Up to date,the MIT from the perspective of alternation current(AC)transport and its potential electronic applications remains yet unclear.Herein,we demonstrate the frequency(f_(AC))dependence in the impedance(Z=Z’+iZ″)of typical MIT materials,such as thin film rare-earth nickelates(Re NiO_(3)),across the critical MIT temperature(T_(MIT)).Apart from the abrupt change in the impedance modulus(|Z|)across the critical temperature(T_(MIT))similar to the DC transport,the MIT also triggers non-continuous variation in the impedance phase(θ),and this enables the f_(AC)-regulations in the Z’-T tendencies(Z’=|Z|cosθ).At the critical f_(AC) range(e.g.,104-106 Hz),the con-versing variations in|Z|-T and cosθ-T across T_(MIT) result in non-monotonic delta-shape Z’-T tendency in Sm_(x) Nd_(1-x) NiO_(3),the full width half maximum of which is effectively narrowed compared to the situation with the absence of MIT.Further imparting lower or higher f_(AC) elevate the domination in|Z|-T and cosθ-T,respectively,but also enables abrupt Z’-T tendencies across T_(MIT) showing negative temperature coefficient of resistance(NTCR)or positive temperature coefficient of resistance(PTCR).By introducing f_(AC) as a new freedom,the MIT behavior can be more comprehensively regulated electronically,and this extends the vision in exploring the new electronic applications based on the correlated MIT materials from the AC perspective. | Haifan Li Fanqi Meng Yi Bian Xuanchi Zhou Jiaou Wang Xiaoguang Xu Yong Jiang Nuofu Chen Jikun Chen | 2023 | Journal of Materials Science & Technology2023，，17： | 1 |

| 9 | Semi-chemical interaction between graphitic carbon nitride and Pt for boosting photocatalytic hydrogen evolution显示文摘Owing to the exorbitant overpotential and serious carrier recombination of graphitic carbon nitride(gC_(3)N_(4)),noble metal(NM)is usually served as the H_(2)evolution co-catalyst.Although the NM(such as Pt)nanoparticles can reduce the H_(2)evolution overpotential,the weak van der Waals interaction between Pt and g-C_(3)N_(4)makes against the charge transfer.Herein,the solvothermal method is developed to achieve semi-chemical interaction between Pt and g-C_(3)N_(4)nanotube(Pt-CNNT)for fast charge transfer.Moreover,the generated in-plane homojunction of CNNT can accelerate charge separation and restrain recombination.Meanwhile,the metallic Pt is an excellent H_(2)evolution co-catalyst.Photo/electrochemical tests verify that the semi-chemical interaction can improve photogenerated charge separation and transferability of CNNT.As a result,the photocatalytic H_(2)evolution turnover frequency(TOF)of Pt-CNNT under visible light irradiation reaches up to 918 h^(-1),which is one of the highest in the g-C_(3)N_(4)-based photocatalysts.This work provides a new idea to improve the charge transfer for efficient photocatalytic H_(2)evolution. | Ziai Zhong Lisha Chen Longshuai Zhang Feiyao Wu Xunheng Jiang Haiyan Liu Fengrong Lv Haiyang Xie Fanqi Meng Lingling Zheng Jianping Zou | 2022 | Chinese Chemical Letters2022，33，6： | 1 |
| 10 | Anchoring Single Nickel Atoms on Carbon-vacant Carbon Nitride Nanosheets for Efficient Photocatalytic Hydrogen Evolution显示文摘Polymeric carbon nitride(PCN)has emerged as a promising candidate for photocatalytic hydrogen evolution,but its dependence on scarce and high-cost noble metal co-catalysts severely limits its extensive application.It will be of great promise to develop non-noble metal single-atom co-catalysts with low-cost and high atom utilization to improve the photocatalytic performance over PCN.Herein,single Ni atoms are successfully anchored onto carbon-vacant PCN nanosheets(CCN-SANi)via a two-step ammonia thermal treatment and photo-deposition process.Theoretical calculations and experimental results demonstrate that the optical absorption property and the charge transfer ability of CCN-SANi have been significantly improved with the introduction of single Ni atoms to form Ni-N3 sites.In comparison to carbon-vacant PCN(CCN)loaded with Ni clusters,the obtained CCN-SANi exhibits 11.4 times increased photocatalytic performance,with the highest hydrogen evolution rate reaching 511μmol/(g·h),which is even 1.7 times higher than that of CCN loaded with Pt clusters.This research proposes an inspiring and reliable strategy to design novel single-atom semiconducting polymers with electronic structures manipulated for efficient photocatalysis. | LIN Zhi ZHANG Zhengqi WANG Yiqing PENG Zhiming WANG Xinxin WANG Ruizhe HUANG Yu-Cheng MENG Fanqi LI Mingtao DONG Chung-Li ZHANG Qinghua GU Lin SHEN Shaohua | 2022 | Chemical Research in Chinese Universities2022，38，5： | 1 |

| 12 | High coercivity cobalt carbide nanoparticles as electrocatalysts for hydrogen evolution reaction显示文摘Cobalt carbide nanoparticles(NPs),as a typical carbide material,have attracted extensive attention in the fields of magnetism and electrochemistry.Herein,we adopted a modified solution route by pyrolysis long-chain amines at high temperatures to obtain Co_(2)C NPs,in which different forms of Co NPs were used as precursors.The results reveal that no matter what the structure of the precursor and the type of long-chain amine,single-phase Co_(2)C NPs with good crystallinity are obtained.At the same time,carbonization of hexagonal close packed(hcp)cobalt as the precursor gives the materials high magnetic anisotropy,exhibiting a large coercivity(~1,300 Oe)on the nanoscale.In terms of catalytic properties,benefiting from intrinsically high activity of Co_(2)C NPs,the material demonstrates superior hydrogen evolution reaction(HER)performance,with optimal overpotential as low as 73 mV at the current density of 10 mA·cm^(-2).This provides new ideas for the further development of transition metal carbides(TMCs)and the improvement of their magnetic and electrocatalytic properties. | Yaqin Qie Yixuan Liu Fanqi Kong Zhilin Yang Hua Yang | 2022 | Nano Research2022，15，5： | 1 |

| 17 | Gold-vapor-assisted chemical vapor deposition of aligned monolayer WSe2 with large domain size and fast growth rate显示文摘Orientation-controlled growth of two-dimensional(2D)transition metal dichalcogenides(TMDCs)may enable many new electronic and optical applications.However,previous studies reporting aligned growth of WSe2 usually yielded very small domain sizes.Herein,we introduced gold vapor into the chemical vapor deposition(CVD)process as a catalyst to assist the growth of WSe2 and successfully achieved highly aligned monolayer WSe2 triangular flakes grown on c-plane sapphire with large domain sizes(130μm)and fast growth rate(4.3μm·s^−1).When the aligned WSe2 domains merged together,a continuous monolayer WSe2 was formed with good uniformity.After transferring to Si/SiO2 substrates,field effect transistors were fabricated on the continuous monolayer WSe2,and an average mobility of 12 cm^2·V^−1·s−1 was achieved,demonstrating the good quality of the material.This report paves the way to study the effect of catalytic metal vapor in the CVD process of TMDCs and contributes a novel approach to realize the growth of aligned TMDC flakes. | Mingrui Chen Anyi Zhang Yihang Liu Dingzhou Cui Zhen Li Yu-Han Chung Sai Praneetha Mutyala Matthew Mecklenburg Xiao Nie Chi Xu Fanqi Wu Qingzhou Liu Chongwu Zhou Mork | 2020 | Nano Research2020，13，10： | 1 |
